IMPROVEMENT IN UMBRELLA-RIBS.

Specification forming part of Letters Patent No. 159,624, dated February9, 1875,' application led November 24, 1874.

To all whom it may concern:

Be it known that I, HENRY WINTER, of Jersey City, in the county ofHudson and State of New Jersey, have invented an Improvement in Umbrellaand Parasol Frames, of which the following` is a specification:

Steel wires have heretofore been used for unibrella and parasol ribs,and at the end of the rib that is jointed to the crown it is usual toflatten the metal and punch a hole in the same. In doing this the metalis often injured, and the joint breaks either in the manufacture or inuse, and this risk is increased by the thin iiattened end becoming toohighly heated in hardening process.

My improvement relates to making the joint at the end ot' the steel Wirerib out of sheet metal, whereby greater strength is obtained and thejoint can be repaired it' broken,`

instead of the rib becoming entirely useless, as heretofore.

I Ina-ke use of a strip of sheet metal that is folded in the middle toform the eye, and the end portions are bent into trough shapes tosurround the end of the rib and clasp the same while being soldered toplace. By this improvement it is not necessary to form the sheetmetaltip into cylindrical shape, as has heretofore sometimes been done, andthe eye is in the strongest portion of the metal.

In the drawing, Figure 1 is a View of part of the umbrella-frame attheerown. Fig. 2 is a plan View of the saine. Fig.- 3 shows thesheet-metal blank, as eut out, and Fig. 4 shows a side View of thesaine. Figs. 5 and 6, different views of the same, as bent up ready tobe applied to the rib.

The rib a is preferably of' steel Wire, and the end thereof is simply inthe condition in which it is eut olf. The clip bis eut out of sheetmetal, preferably in the form shown in Fig. 3, with the tongues 2 2 andelaspingpoints 3 3, but the olasping points 3 may be omitted. Thetongues 2 2 are eaeh bent up into a trough shape, as seen in Fig. 4, andthen the clip is bent in the middle to forni the eye 4, as seen in Fig.5, or to receive a hole, as in Fig. 6, for the erown Wire, and the endoi' the wire rib a is inserted into this eli p and soldered. It' thepoints 3 3 are used, they are bent up-to clasp around the portions 2 ofthe elip and hold the same together and to the end of the rib previousto soldering the parts of the clip to eaeh other and to the rib.

I claim as my invention- The clip at the end of the umbrella or parasolrib, made of a strip ot' sheet metal folded to form the eye, and bent toconform to the shape of the rib and soldered thereto, as set forth.

Signed by me this 20th day of November, S74.
